While overlooking the Missouri river from the north side of Bismarck in a stagard V formation, 5 lights (not sure if one object or 5 objects) were noticed in the north sky and completely crossed the sky in 6 seconds.

Other witness saw it first and say that it was redish for a split second but all 6 seconds I observed it they were white lights.

No trails behind lights and no sound. Amazingly fast but could never have been satellites or shooting star.
